EditText 입력값 다른 Activity 에서 출력하기

다른곳도 수정해야 하지만 파란색도 빠트리지 말고 수정해줍니다.

Code for MainActivity.java file.

package com.passedittextvalue_android_examples.com;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends Activity {

 EditText SendValue;
 Button SendEditTextValue;
 Intent intent;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 
 SendEditTextValue = (Button)findViewById(R.id.button1);
 SendValue = (EditText)findViewById(R.id.editText1);
 
 SendEditTextValue.setOnClickListener(new View.OnClickListener() {
 
 @Override
 public void onClick(View v) {
 
 intent = new Intent(getApplicationContext(),SecondActivity.class);
 intent.putExtra("EdiTtEXTvALUE", SendValue.getText().toString());
 startActivity(intent);
 
 }
 });
 }
}

Code for activity_main.xml layout file.

 android:layout_width="match_parent"
 android:layout_height="match_parent"
